DMARC Record Checker

Check and validate your domain's DMARC record. See your policy, report addresses, and common misconfigurations.

What is a DMARC record?

DMARC (Domain-based Message Authentication, Reporting and Conformance) is a DNS TXT record at _dmarc.yourdomain.com. It tells receiving servers what to do with mail that fails SPF or DKIM, and where to send reports. A strong DMARC policy protects your domain from spoofing and improves deliverability.

DMARC policies

  • p=none monitors only, no enforcement.
  • p=quarantine sends failing mail to spam.
  • p=reject blocks failing mail outright (the strongest protection).

Also check your SPF and DKIM records.
